SPINNING AND TWISTING MACHINE SPINDLE.

SPECIFICATION forming part of Letters Patent N o. 643,343, dated February 13, 14900.

' Application tied materialistas; serenata-15o. camini.)

clare that the following is a full, clear, and l exact description of the same, reference being hadto the accompanying drawings7 forming part of this specification.

This invention has reference to an i mprove-` ment in spinning and twisting machine spindles in which the spindle and Vthe drivingwhirl are disconnected and may rotate one independent of the other, of which, as far as I know, I am the original inventor.`

The object of my present invention is toY facilitate the independent automatic adjustment of the spindle and the drivin g-whirl and economize power.

The invention consists in the peculiar and y novel construction by which the spindle and the tube forming the support for the drivingwhirl rest on a series of balls, whereby the foot of the spindle and the foot of the whirlsupporting tube may move laterally through a limited distance and rotate on the supporting-balls.

Figure ll is a vertical sectional view of my improved spindle, showing the same provid ed with abobbin. Fig. 2 is a side View, and Fig. 3 a sectional view, of the bolster. Fig. 4 is a side view, and Fig. 5 a sectional view, of a tube secured to and forming the support of the sleeve-whirl. Fig. 6 is a side view of the lower part of the spindle. Fig. 7 is a transverse sectional view of the bolster-case immediately above the enlarged foot of the spindle. Fig. 8 is a'sectional view of the sleeve- Whirl.

Similar marks of reference indicate corresponding parts in all the ligures.

In the drawings, a indicates the bolster-case,

l which may be of any one of the usual types adapted to be secured to the bolster-rail of the machine. In the preferred form shown in the drawings the bolster-case is provided with the annular flange a by which it rests on thebolster-raihwith the nut a2 on the lower screw-threaded portion by which it is secured to the bolster-rail, and with the laterally-ex- A end with the slightly-conical hole b' and at its lower y end with` the whirl b2 and preferably with the cup b3, which forms a socket for the receptionof the lower end of the bobbin.` The tube b4 has a slightly-tapering upper end b5,wl1ich when driven into the tapering hole b in the sleeve-whirl b firmly secures the tube b4 in the sleeve-whirl. l The bearings b and 127 `on the tube b4 iit the interior of the bolster a5 with a loose sliding fit. g n

The lower end of the spindle c is provided with the cylindrical enlargement c', and at the junction of the spindle c with the enlarge- I ment o the concave bearing-groove c? forms the race for the vseries of balls c3. The foot of the spindle c4 is supported on the series of balls c5, and the spindle c extends through the tube b4 and may freely rotate in the same, having sufficient freedom to permit of the lateral motion in all directions 'required to yield to an unbalanced load. The blade c6 ot' the spindle supports the upper end of the bobbin d, the lower end of which is supported on the sleeve-whirl I), which is vertically supported by the tube b4, resting on the series of balls c3. As the tube b4 is sufficiently loose in the bolster a5 to permit of automatic lateral adjustment the foot of the tube mayr move laterally on the balls c3. By this construction the spindle may rotate independently of or with the sleeve-whirl. With the upper end of the bobbin d in adhesive frictional contact with the blade c6 of the spindle, the spindle and the sleeve-whirl will rotate together, being connected by means of the bobbin. When l the bobbin is removed, the sleeve-whirl continues to rotate, being driven by the drivingband, and the spindle will remain stationary or creep around by occasional contact with the tube b4.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a spinning or twisting machine spindle, the combination with a sleeve-Whirl -having a supporting-tube inclosing the spindle but loose on the same and the live-spindle, of the series of balls ccs forming the vertical support of the sleeve-whirl and the series of balls c5 forming the vertical support of the spindle, as described.

2. In a spinning or twisting machine spindle, the combination with the bolster-case c, the bolster a5 secured in the bolster case against rotation and the step a7, of the livespindle c having the cylindrical enlargement c', the groove c2 and the conical foot c4, the sleeve whirl Z9 having the tube b4 secured thereto, and the series of balls c3 and c5 forming the vertical support of the sleeve-Whirl and of the spindle; whereby the sleeve-whirl may rotate independent of or with the spindle supported on the ballbearing, as described. p

3. In a bobbin-support, in combination, a bolster-case, a live-spindle rotatably supported inthe bolster-case, an annular groove in the spindle adapted to form the race for a ball-bearing, a sleeve-whirl having a supporting-tube inclosing the spindle but loose on the same and a series of balls in the annular groove of the spindle; whereby the sleevewhirl is vertically supported on the balls and may turn on the spindle, as described.

In witness whereof I have hereuntoset my hand.

.HENRY F. VVOODMANOY.
